Application filed February 5, 1918. Serial No. 215, rz7.

To all whom it may CWtt't:

CHARLES FREDERICK United States, and a resident of the city of Seattle,in the State of Washington, United States of America, have invented newand useful Improvements in Wheel-Flange Gil-Distributers for Lubrieatingthe Flanges of Track-Vehicle Wheels, of which the following is aspecification.

his invention relates to wheel flange lubricators'of the type disclosedin my companion application Serial N 0. 171,566, dated May 28, 1917, theobject of my present invention being to provide a simple, reliable dinexpensive device, and it consists in the constructions, combinationsand arrangements herein described and claimed.

Another object of my invention is to provide an oil distributer shoe,having an end adapted to fit over a wheel flange, and having alongitudinal cavity therein which provi es a source of least resistancewhich the normal wearing action of a revolving wheel flange will follow.

A further object of my invention is to provicle means for equalizing thenormal wear within the discharge end of the oil distributer shoe, andto-that end I have designed ahollow distributer shoe, having walls ofsuch relative proportions to each other, that the walls on either sideof the wheel flange will feed-up fresh material, thereby compensatingfor lateral wear on their inner surfaces.

A still further object of my invention is to provide a detachabledistributer shoe, of simple construction, and conveniently arranged forrenewing the same as needed.

Other objects and advantages will appear in the followingspecifications, and the novel features of the device will beparticularly pointed out in the appended claims.

y invention is illustrated in the accompanying drawings forming part ofthis application, in which igure 1 is a view in side elevation, of aportion of a wheel flange, showing the oil distributer applied thereto.

F ig. 2 is a view in front elevation, of the wheel flange oildistributer.

Fig. 3 is a side plan view of the oil distributer shoe, showing a cavityextending longitudinally therein by dotted lines.

Fig. 4 is a sectional view of a portion of a wheel flange, and a topplan view of the oil distributer nal cavity and oil pipe by dottedlines.

Fig. 5 is a top plan view of a tapered look ing key.

Fig. 6 is a section on the lineBB of Fig. 4.

In carrying out my invention I have provided a bracket frame of a cartruck by means of a bolt 3, or any similar form of attachment. In theend of the bar 2 adjacent the oil distributer, is a counter-sunk hole oreye 5, from which is suspended a hanger 6, bearing in its lower end acomparatively large opening or loop :7, adapted to have detachablysecured therein the reduced end 8 of the distributer shoe 9. Saiddetachable means employs a con- Means for holding the key 11 in itsrespective position is provided by the spring 13, which has its centralportion passed over the attaching bar 2 and the portions on each side ofthe center being wound around their respective spring bosses or lugs 4and 4*, having the ends extended over their respective grooves 14 and 14The spring 13 is also adapted for the further purpose of holding thedistributor end 15 of the shoe 9 in contact with a revolving wheelflange, as shown in Fig. 1.

Referring .now to the construction of the distributor shoe 9, whichmay-beef any suit able material but preferably of cast steel, it isprovided with an oblong cavity 16 (shown by dotted lines in Figs. 3 and4), having relatively proportioned wallsl7, 18, 19 and 20, so as toequalize the normal distributer shoe end 15 when the same is engagedwith a revolving wheel flange. This cavity having properly proportionedwalls serves as a source of least resistance which the wearing-action ofa revolving wheel flange will follow. Thus it is seen that byconstructing the walls as shown in Fig. 6, the shoe will submit to acontinued feedingup action against the wheel flange. The wall 18 beingthe thickest of the walls, is

shoe, showing the longitudi subjected to the tread of the wheel as wellas to the tread side of the flange, thereby receiving the most wear,while the opposite wall 17 is subjected only to the opposite side of theflange and receiving lateral wear only. It will be seen that the walls19 and 20 will give way to a wearing action of the wheel flange fully asfast as the wall 18 will permit them to feed-up. Thus a continuefeeding-up of fresh material to compensate for the lateral wearingaction within the shoe end is accomplished, thereby mambeing applied.

taining a comparatively snug fit over the wheel, flange. A. pipe 21extends parallel with and partially within the wall 18, having itsdischarge opening 23 in position for engaging the tread side of thewheel flange 1, while its end'opposite 22 projects through the reducedend 8 forming a nipple to which a hose or other flexible tube may beattached.

It should be understood that the distributer shoe may be constructed inpairs of right and left,,for discharging oil to the thread side of awheel flange of either the right or left wheel of a car truck.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood.

A lubricating fluid tributer, by means of attaching a hose or otherflexible tube to the nipple 22 The 2 is bent so as to conform itself tobeing attached to the frame of a car truck forholding the device inposition to lubricate the flanges thereof. en in its normal position thespring 13 holds the distributer shoe in its attachment with its hangerby means of the tapered locking key 11, and simultaneously holds thedistributor shoe in contact with the wheel flange. en it becomesnecessary to renew the distributor shoe, the ends of the spring 13 maybe lifted out of their respective grooves 14 and 14 and the key 11driven out of the loop 7, thus releasing the shoe preparatory to a newone It is obvious that various are within the scope vvention, and

modifications and spirit of this in- I' do not limit myself to thespecific construction shown.
